IMPROVEMENT IN VAPOR-BURNERS.

Specifica-tion forming part of Letters Patent No. 57,276, dated August21,1866.

To all whom 'it may concern:

Be it known that I, W. W. BATCHELDER, of New York, in the county andState of New York, have invented certain new and useful Improvements iuCoah Oil Burners; and I hereby declare the following to be a full,clear, and exact description of the same, reference being had toaccornpanyin g drawings, in Which- Figure l represents a plan View frombeneath of that part oi' a coal-oil burner to which my improrements areapplied. Fig. 2 is ahorizontal section ou the line :c x, Fig. 3; andFig. 3 is a vertical section on the line y y, Fig. l.

My invention relates to coal-oil burners in which the oil is vaporizedand mixed with atmospherie air so as to form a gas, which is i gnited atthe point where it issues from the top of the burner,A and burns with aclear tlame without the aid of a chimney.

The object of my invention is to so arrange the parts of such a burnerthat, no matter how little light is desired, or to what extent theila-me is diminished, there shall be no smoke nor disagreeable odorgenerated, but the gas formed shall still continue to burn with a clearand steady flame.

My invention consists in interposing `bet-Ween the Wick tube orholder.and the vaporizinga chamber of a coal-oil burner, as abovedescribed, a movable and adjustable diaphragm so arranged th atthe slotoropening in itthrough which the products ot" combustion enter thevaporizing-chamber may be made larger or smaller, according as the wickis raised or lowered, or, in other words, according to the degree oflight required. The slot or opening in the diaphragm should-be in thesame vertical plane with the opening in the wick-holder from which thewick projects; and, in order to secure a more steady tlame, I arrangeboth of these openings so that they shall be at right angles, or nearlyso, to the slot in the top of the vaporizingchamber through which thegas esbeing compressed and brought together at the top, so as to form aslot, et, from which the yapor passes. It is surrounded by a dome, B, inwhich a corresponding opening, a', is formed, as is seen in any ordinaryburner ot' this kind. The dome has its seat in a liange formed for itsreception in tne lamp cap or top O. At the lower end of thegenerating-chalnber A is a stationary plate or diaphragm, D, which issecured to the sides of the dome B. This plate has an opening in thecenter at right angles, or nearly so,vto the slot a in the top of thevaporizing-chamber A, through which the products ot' combustion, whenthe Wickisignited, pass into the chamber A.. It also has openings aroundits sides, through which the air aseeuds into the dome B. To the underside of this plate are secured the segmental plates E E', which formthe. movable or adjustable diaphragm. They are secured one on each sideot' the openingI in the stationary dia phragm D, their straight edgesbeing opposite each other. In this latter plate or diaphragm, and onbot-h sides of the opening referred to, are cut the diverging slots b bb b'. These slots commence at the central opening, and thence exten d asuitable distance in a diagonal direction, as shown in Figs l and 2, thetwo slots on the same `side ofthe opening being parallel to each other.To the Lipper side of the movable platesE E are fastened pins or studs cc c' c', which lit in the slot-s just de- I scribed.

The plates are actuated, as shown in the drawings, by means of Wires orsmall rods e, which are pivoted or secured to the under side of eachplate, and, Vthence extending out through the sides of the dome B, arebrought together and held by a knob or butt-on, d, ot' wood or othersuitable non-conductor ,of heat.

The eect ot' this arrangementis as follows: lf the wires `be pulled bymeans of thekuob d, the plates E E', which constitute the movable partofthe diaphragm, will, by meansA of the pins or studs c c sliding in theslots b b', be drawn together, as shown in Fig. 1, until their oppositeand parallel edges are in contact. When inthisposition the products otlcombustion must'pass through the small slot or opening vk, which isformed by cutting out a small recess in each edge. It' the knob d be now pushed in toward the dome B, the studs c c' i Willbe forced back inthe slots b b', thus separating the. segmental plates E E and causingthe gradual enlargement of the openingin the diaphragm until the platesare moved back so as to expose the whole opening, as shown in Fig. 2. l

As shown ,in Fig. 3, the diaphragm is arj ranged so that the opening init shall be at right angles to the opening in the top of thevapor-chamber A.

In order to use the burner, the Wick in the wick-holder F is flrstlighted, and then the dome Bis set in place, care being taken to havethe diaphragm open to its full extent.`

A light is then applied to the opening in the top of the burner, and ina moment or two the gas whichv has been generated by the mixture of thevapor with the atmospheric air escapes from the top of the burner andbecomes ignited.

Now, in order to prevent the escape of the smoke and disagreeableodorwhich are usually noticeable in ordinary lamps of this kind, themovable diaphragm is adjusted by means of Athe knob d and wires e untilthe opening in its center is just sufficient to allow the pro! ducts ofcombustion to pass into the chamber A,'without being' large enough toallow the be in a direction corresponding to that of ther opening in thetop of the burner, instead of being at angles thereto, as abovedescribed, though I consider the latter arrangement more advantageous,for the reasons hereinbefore stated.

rlhe movable diaphragm itself may also be actuated in many differentways from that herein shown without departing from the principle of myinvention.

What I claim, therefore, and desire to se-` secure by Letters Patent,is`

l. Regulating and steadying the llame of a coal-oil or other similarlamp in the Vmanner and by the means herein specified-that isto say, byinterposing between the vaporizingchamber and wick tube or holder of alampburner constructed as above described a mov-Y able and adjustablediaphragm, as and for the purposes hereinbefore shown and set fort-h.

2. The movable and adjustable diaphragm, as herein described, the sameconsisting of a perforated stationary plate, in combination with movableplates of segmental or oth er suitable shape, constructed and arrangedfor operation substantially as and for the purposes herein set forth.

. 8. In combination with the vapor-'chamber yand surroundingdome and thewick-tube of a coal-oil o r other burner, as described, the movable andadj ustable diaphragm, constructed .as herein specified, the whole beingarranged for operation substantially as set forth.

In testimony whereof [have signed my name to this specification beforetwo subscribing witnesses.
